Some thirty young voices blend seamlessly in Saranga. The music is simple but steeped in rich bhava and leaves you with moist eyes by its sheer earnestness. It is Suguna Purushothaman’s class at her Abhiramapuram residence. Some of today’s concert singers are part of the group that impacted you that day, more than a decade ago. Suguna Mami keenly absorbs each singer’s output, silently assesses, processes in her mind and makes pertinent observations. She corrects a posture here and mildly ticks off a closed mouth effort there. “Saranga should not be pushed too much, you know. It can sound like Hamir Kalyani or even morph into Kalyani,” she warns. As she deftly demonstrates the dangers that lurk, the children listen carefully. Many little boys are a part of the group too. The music continues and melts your heart. The song is over. Suguna Mami comes up with a joke that eases the mood of the class. Within seconds they are singing again, to rehearse for a group performance coming up soon.
